I'm using the SearchGrammar.cs from the examples for a FTS application.
I want to change the syntax to only identify the "-" binary operator if its
NOT followed by a whitespace.
1. word1 - word2
Should generate ((WORD1) AND (WORD2)) , "-" was removed because there is a white space after the operator.
2. word1 -word2
Should generate ((WORD1) AND NOT (WORD2)) , "-" was removed and replaced by AND NOT.
